 ASP.NET Core provides support for custom parameter binding in Minimal APIs using the <xref:Microsoft.AspNetCore.Http.IBindableFromHttpContext%601> interface. This interface, introduced with C# 11's static abstract members, allows you to create types that can be bound from an HTTP context directly in route handler parameters.

 By implementing the <xref:Microsoft.AspNetCore.Http.IBindableFromHttpContext%601>, you can create custom types that handle their own binding logic from the HttpContext. When a route handler includes a parameter of this type, the framework automatically calls the static BindAsync method to create the instance:
